i have a handful of Xzero spare parts if anyone is short something?

I've rebuilt my predator and mini raptor and have a number of parts that i don't need from the original now.

These are all "new" but will be probably scratched up a little - especially the predator ones which were kicking around the shop and storage a while.

Mini raptor:

- 50x50 x "18" main extrusions.
- "18" wide lower cross beam extrusion
- 3pc ball screw bearing mount blocks fixes side
- 2pc ball nut mount block y/z
- 1pc ball nut mount block x (bottom)
- "24" 20mm X ball screw. cheap chinese one.

Predator:

- Y saddle - cut for modification to access grease fitting
- Z saddle - cut for modification to access grease fitting
- Z main bake plate - some drilled and machined modifications
- Z ball screw 2510 tbi
- Z ball screw support block fixed
- X ball screw support block fixed
- X ball screw support block free
- Z ball nut mount block
- nema 34 motor mount
- "48" x ball screw 2525

If you ended up missing something, or damaged something and need one, let me know.

Hi my name is Joe and I have owned a predator 40 x 48 for the past 6 years. I recently discovered that my gantry leadscrew (the one that is 25 dia x ~40" long) is bent. The machine has always had a problem with binding and the Covid-19 lockdown has given me the time to diagnose the issue and narrow it down to a bent screw.
Does anyone out there have a spare one? I sent a note to George as well, but not sure he is still in business.

I have a 48" one, you'd need to cut it and turn the end back down for the bearing, so I don't know if that's useful to you.

Thanks for the quick response!!
I may be able to turn the end of the screw to work, but not sure. I have tried turning ballscrews before without too much luck , even with ceramic cutters. Also, it looks like the design of the bearing/screw assembly depends on the bearings being press-fit onto the screw ends. Any advice on the bearings? How much do you need to get for the screw?

thanks again, I really appreciate it.

You only need to turn the floating end, which is much more forgiving. main thing is keeping it concentric. it does not need a super tight press fit. slip fit will do. you don't want more than about .002" of paly.

Price, dunno $250 (this is the tbi 2525 screw), the main issue will be shipping as its too large for the standard services. I'm not sure I can even ship at all "now", and you cant cross the border. Ha!
